The Effects of DWI ‐Infarct Lesion Volume on DWI‐FLAIR Mismatch: Is There a Need for Size Stratification?

CONCLUSIONThe effects of stroke onset‐to‐scan time gap on DWI‐FLAIR mismatch are not the same for different DWI lesion volumes. At DWI lesion volumes >15 mL, the DWI‐FLAIR mismatch is highly specific for acute infarcts within IV thrombolytic therapy time, and can identify wake‐up stroke patients eligible for treatment.
